BSD licenses represent a family of permissive free software licenses. The original was used for the Berkeley Software Distribution, a Unix-like operating system for which the license is named. The original owners of BSD were the Regents of the University of California because BSD was first written at the University of California, Berkeley. The first version of the license was revised, and the resulting licenses are more properly called modified BSD licenses. Permissive licenses, sometimes with important differences pertaining to license compatibility, are referred to as "BSD-style licenses". Image File history File links BSD-daemon. ...

The licenses have few restrictions compared to other free software licenses such as the GNU GPL or even the default restrictions provided by copyright, putting it relatively closer to the public domain. The BSD licenses have been referred to as copycenter, as a comparison to standard copyright and copyleft free software: "Take it down to the copy center and make as many copies as you want." GNU (pronounced ) is a free operating system consisting of a kernel, libraries, system utilities, compilers, and end-user applications. ...

Proprietary software licenses compatibility The BSD License allows proprietary commercial use, and for the software released under the license to be incorporated into proprietary commercial products. Works based on the material may even be released under a proprietary license (but still must maintain the license requirements). Some notable examples of this are the use of BSD networking code in Microsoft products, and the use of numerous FreeBSD components in Mac OS X. Microsoft Corporation, (NASDAQ: MSFT, HKSE: 4338) is a multinational computer technology corporation with global annual revenue of US$44. ...

It is possible for something to be distributed with the BSD License and some other license to apply as well. This was in fact the case with very early versions of BSD itself, which included proprietary material from AT&T. This article describes the present AT&T Inc. ...
UC Berkeley advertising clause As originally distributed, the BSD license had an extra clause, requiring authors of all works deriving from a BSD-licensed work to include an acknowledgment of the original source. This is numbered as clause 3 in the original licence text: * 3. All advertising materials mentioning features or use of this software * must display the following acknowledgement: * This product includes software developed by the University of * California, Berkeley and its contributors. The GNU project called this clause "obnoxious", citing the requirement for 75 such acknowledgments when advertising a 1997 version of NetBSD[1]. A large legal problem was that the advertising clause was incompatible with the terms of the GPL (which does not allow the addition of restrictions beyond those it already imposes) thus forcing a segregation of GNU and BSD software. The GNU project suggests people not use the phrase "BSD-style" licensing when they wanted to refer to an example of a non-copyleft license, in order to prevent inadvertent usage of the original BSD license.[1] GNU (pronounced ) is a free operating system consisting of a kernel, libraries, system utilities, compilers, and end-user applications. ...

Further, people who made changes to the source code tended to want to have their names added to the acknowledgement. This is problematic since with large numbers of people working on a single project (or for many separate projects in a software distribution), the advertising clause quickly created large and unwieldy acknowledgements.
This '4-clause' advertising version was removed from the official BSD license text on July 22, 1999 by William Hoskins, the director of the office of technology licensing for Berkeley, in response to a request from Richard Stallman.[2] Other BSD distributions followed suit, but NetBSD still uses the original version of the license and many similar clauses remain in BSD derived code from other sources.

The original license is now sometimes called "BSD-old" or "4-clause BSD", while the current revision of the BSD license is sometimes referred to by the by names including "BSD-new", "revised BSD", or "3-clause BSD".
BSD-style licenses Several free or open source licenses that derive from or are similar to the BSD license are widely used: - NetBSD still uses a 4-clause license equivalent to the original BSD license.
- A 2-clause BSD-like license also exists which deletes the third clause, prohibiting use of the copyright holder's name for endorsement purposes. Removal of that clause makes the license functionally equivalent to the MIT License. This is the only BSD-style license permitted for certain libraries included in KDE.
- FreeBSD also uses a 2-clause license with an additional statement at the end that the views of contributors are not the official views of the FreeBSD Project.
- OpenBSD uses a license modeled after the ISC license for all additional software created by the project, as it is functionally a two-clause BSD-styled license, with no additional clauses or consequences involved.
- The University of Illinois/NCSA Open Source License combines text from both the MIT and BSD licenses, and is equivalent to the 3-clause BSD license.
- Xiph.Org Foundation uses a 3-clause license for the binary libraries of their different projects.
